Immunoassays are commonly used by the clinical laboratory, but paraproteins can occasionally produce erroneous results. In this study, we investigated the cause of apparent false positive results for multiple Kinetic Interaction of Microparticles in Solution (KIMS) immunoassays. Patient controls and samples containing the interference were analyzed using automated chemistry platforms, gel electrophoresis, immunofixation, affinity chromatography, and size exclusion chromatography. Our results show that IgA paraprotein caus
